IGNITION-CIRCUIT CONNECTION.

Specification of Letters Patent.

Patented Jan. 7', 1908.

Application filed May 13, 1907- Serial No. 373.339

To all whom it may concern:

Be it known that I, EDWIN liinoorn, a citizen. of the United States,residing at Brookline, in the county of Norfolk and State ofMassachusetts, have invented cer tain new and useful improvements inIgnition-Circuit Connections, of which the followi is a specification.

y invention relates to electrical coi'mections whereby several sourcesof electric energy, preferably a generator, a storage batbe connected tothe ignition circuit of explosive engines for the purpose of supplyingelectricity thereto, and has for its object to provide a system ofintercomiecting said sources of electricity by controlling switches soto bring said sources of electric energy into the desired relations asto each other, and as to the ignition circuit, with a minimum equip mentof electric wiring and apparatus.

Figures 1' and 2 are diagrammatic views showing the preferred form inwhich my invention may be embodied, the switch blades of the maincontrolling switch being shown in their down position in Fig. 1, and intheir u position in Fig. 2. Figs. 3 and 4.

' preferably of are simi a1 views showing another form in whichmy'invention may be embodied.

In said Fig. 1, 1 is an electric generator, preferably adapted to beactuated by the motor whose ignition system it is desired to energize. 2is a storage battery also adapted to supply electric current to said.ignition 35.

system, and furthermore designed to be c arged by said generator. At 3is a battery,

dry cells, by which said ignition system may be energized independentlyof the generator or the storage battery. The terminals of the circuitleading to the ignition system are shown at 4 and 5, one lead preferablyconnecting with the spark coil, and 'the other lead being grounded onthe motor.

At 6 is shown the main controlling switch, which is preferably of thedouble pole, double throw, single break type, having the movableconductors or switch blades 7 and 8 pivoted at hinge posts 9 and 10, andrespectively-engaging in one position of switch with contacts 11 and 12,and in the other position ofswitch with contacts 13 and 14A. Thegenorator switch 15 is preferably of the double pole, single throw,single break type, having switch blades 16 and 17 adapted to connecthinge posts 18 and 19 with contacts 20 and. 21.

and generator switches are connected to each other and to the generator,dry, and storage batteries, is as follows. Contact 11 is wired to onepole of dry battery 3, its other pole being connected with ignitioncircuit lead 4. Ignition circuit lead 5 is wired. to hinge post 9, andhinge post 10 is connected to ono'polc of generator 1, the other polebeing wired to contact 19 of switch 1.5. Contact 21 is connected to onepole of storage battery 2 and a branch wire 22 also connects the saidpole with contact 13. The other pole of storage battery 2 is wired. tolead 4 of the ignition circuit, a branch wire 23 also leading to contact20. Contact 18 is in electrical onnection. both with contacts 14 and 12.

The method .of operation resulting from the connections as above setforth is as follows. Supposing storage battery 2 to be inert andgenerator 1, and motor as well, to be at rest, the switch handle isthrown down, causing switch blades 7 and 8 to electrically connect 9 and11, and 10 and 12, as shown in Fig. 1. This closes the circuitconnecting dry battery 3 with the ignition circuit leads; thusenergizing the ignition system and sup plying current for starting upthe motor. When the motorstarts up generator 1 will be actuated thereby.and will begin to'develop electricity for charging the storage battery2, with which it is incircuit through 10, 8, and 12, switch 15, and wire23! I i r When the motor well started the switch blades may be thrown upinto the position. shown in Fig. 2. The dry battery 3 is now no longerin circuit with the ignition system, but current will be now suppliedthereto from the generator, the circuit to lead 4 being closed by theswitch blades 8 and 16, and to lead 5 by switch blades 17 and 7 and wire22. As in Fig. 1 generator 1 is in charging relation to storage battery2 through switch blade 8, switch 15 and wire 23, and will supplycharging current thereto, simultaneously with energizing current for theignition system. When the storage battery is charged, as nray be shownby voltmeter l4, switch 15 may be opened, and the ignition systemsupplied by l the storage battery alone, one pole being di- The wiringby which the main controlling be permanently connected and and switchblade 7.

switch used in Furthermore tuated by automatic meansopeninglor closingcontacts 9 and 11, and 3, it will be seen that, as Fig. 1, the dry batbthe switch when the voltage of battery exceeds termined limits.

Figs. 3 and 4 show another method of interconnecting dry and storagebatteries, enerator, and mam and enerator switc es. As before, a doublepole, ouble throw, single break switch is used as the main switch 6. Thegenerator switch 25 isshown as-of the single pole type. Here, as inFigs. 1 and2, one po e of dry battery 3 is connected to ignition lead 4,the other pole being wlred tocontact 11. I tion lead 5 is connected tohinge post 9. ontacts 12, 13 and 14 are electrically interconnected witheach other, and to contact 26 of generator switch 25. The other switchcontact 27 leads to one pole of generator 1, the other pole of the samebeing wired to one ole of storage battery 2, a branch wire 2811580connecting the same with'ignition lead 4. The other, pole of the storagebattery is wired to hinge post 10.

SWItOh 25 being closed, and switch blades 7 and 8* of switch 6respectively'connecting 10 and 12, as in Fig.

e storage or falls below certain predetery is connected into theignition system circuit, and that neously laced inc storage atte throughswit dh enerator 1 is simultaarging relation to the the circuit beingcompleted 25 and switch blade 8 of switch '6. In the other position ofthe switch 6, where the blades are up,-occupying the position showninFig.4, the generator 1 is placed in charging relation to storage battery2 through blade 8'and switch 25, being also adapted simultaneously tosupply energizing current to the ignitlon circuit leads; the circuit incase of lead 4 being through wire 28, and in case of lead 5 throughswitch 25 and blade 7 of switch 6.. 'As before switch .25 may be 0 enedwhen stora e battery 2 ischarged, and electricity me. e then supplied tothe ignition system fiom the storage battery alone, lead 4 beingdirectly connected with one pole thereof through wire 28, and lead 5being connected with the other ole of said storage battery throughswitch lilades 7 and 8.

It is apparent that in 3 may be used a source of electric energy of anydesired nature whatever, so long as it be independent source of switchplace of dry battery or switch blades are in the claims collectivelyreferred to under the term switch elements.

Having described my invention, I claim,
